Previously, a selectiveflotation separationof feldspar in the presence of HF was proposed by Fuerstenau et al. [] in an acidic environment (pH = 2.1).It was suggested that the HF method can achieve a goodseparationof feldspar andquartzwith a high grade of feldspar and a high-qualityquartz[].However, there is a large amount of chemical activator (HF or NaF) in theflotationsystem, as ...
